1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD8327 series is a high-quality fiber optic serial digital video (SDI) and data transmission
system. The system consists of the OSD8327T transmitter and the OSD8327R receiver, which are
designed to be used as a pair to reliably transport SDI and duplex serial data over fiber for long
distances using 1310nm, 1510nm and CWDM wavelengths. The OSD8327 pair is suitable for point to
point applications.
The OSD8327T accepts one HD/SDI video input signal. It has a SDI equalizer to effectively
compensate for coaxial cable losses such as the Belden 1694A cable. This allows flexibility for
permanent and temporary installations when SDI source is some distance away from the unit. The user
can disable the equaliser with a toggle switch mounted on the front panel.
Both the OSD8327T and OSD8327R have built-in user bypassable automatic reclocking. The units will
lock at 270Mbps, 1.485Gbps and 2.97Gbps. The user can disable the reclocker with a toggle switch
mounted on the front panel. The OSD8327R has HD/SDI received optical power LED indicators on the
front panel displaying <0dBm, <-6dBm, <-12dBm, <-18dBm and <-24dBm. The OSD8327T and
OSD8327R transmit and receive duplex serial data. Supported data are 2 and 4-wire RS485, TTL,
RS422, Manchester, Biphase and RS232 operation from DC to 1Mbps.
1.1.2 APPLICATIONS
▲ Any digital broadcast application
such as studio signal routing and
temporary OB or studio links
requiring HD/SDI transmission plus
duplex serial data
▲ Very high performance surveillance
networks
1.1.3 FEATURES AND BENEFITS
▲ Basic functionality is that of OSD’s
well established OSD8327T/
OSD8327R HD/SDI link plus the
OSD138 multi-protocol serial data
link
▲ 2 and 4-wire RS485, TTL, RS422,
Manchester, Biphase and RS232
operation from DC to 1Mbps
▲ Available with built in user
bypassable automatic reclocking at
270Mbps, 1.485Gbps and 2.97Gbps
▲ Operates from 19.4Mbps to 2.97Gbps
in non-reclocked mode
▲ Compatible with SMPTE 310M,
292M, 259M, 297M, 372M and 424M
▲ Automatic equalisation of up to 350m
@ 270Mbps and 140m @ 1.485Gbps
and 70m @ 2.97Gbps of Belden
1694A cable
▲ Immune to pathological signals
▲ Capable of operation over more than
30km
▲ Capable of running off any
unregulated supply from 10 to 28V
DC
▲ Indication of HD/SDI operating rate

2INSTALLATION AND OPERATION
2.1 INTRODUCTION
This section outlines the methods required to install and operate the OSD8327T and OSD8327R
successfully. It should be studied carefully if damage to the equipment or poor results are to be avoided.
This equipment has been fully tested prior to dispatch and is ready for immediate operation. However it
is advisable to check for external transportation damage before operation. If damage is evident, return
the unit with the packaging to your supplier immediately.
2.2 INSTALLATION
2.2.1 CABLING
Shielded cables should be used on all cabling to provide protection from external electrical events such
as lighting, and switching transients etc. which may cause damage to the unit. All cable shielding must
be grounded at a convenient ground point.
2.2.2 WARNING AND PRECAUTIONS
▲ ELECTROMAGNETIC COMPATIBILITY

interference in which case the user may be required to take adequate measures.
▲ OPTICAL OUTPUT OPERATION
WARNING: Laser Safety: Class 1 Laser Product per IEC/EN 60825-1:20011 standard.
Class 1
The OSD8327 is a Class 1 laser product.
PRECAUTIONS
▲ All service personnel should be provided training as to the hazards of direct viewing of laser
radiation and of the precautionary measures during servicing of equipment
▲ Areas where laser products are installed should be restricted in access to trained service
personnel only and appropriate warning signs posted in the work area.
▲ All laser apertures should be covered by protective covers when not connected to optical

2.2.4 POWER SUPPLY CONNECTIONS
The OSD8327T and OSD8327R require external DC power. The voltage range is +10 to 28V
DC.
Power
should be connected to the power socket located on the front panel of the units and applied as indicated
below;

FIGURE 3: OSD8327 POWER SUPPLY CONNECTIONS
2.2.5 HD/SDI CONNECTIONS
The HD/SDI video-input signal (eg. from camera) is connected to the HD/SDI input BNC connector on
the OSD8327T. The OSD8327T also has two HD/SDI input monitor outputs. Note: The OSD8327T
card version has only one monitor output.

The OSD8327R has two HD/SDI BNC output connectors. Note: Figure 5 drawing shows the module
version. The card version is identical except the power connector being a DB9.
FIGURE 5: OSD8327R VIDEO CONNECTIONS
2.2.6 OPTICAL CONNECTIONS
The optical fiber cable must be terminated with the appropriate optical connector. Before connection,
inspect the ends of the connectors to ensure that no dust or dirt is present as it could contaminate the
modem connector and result in poor performance. If it is necessary to clean the cable connectors, use
isopropyl alcohol and lint free tissue to remove contamination.

8 RS422 INPUT + / RS485 (2W I/O, 4W INPUT +)
FIGURE 6: DATA CONNECTOR PIN ASSIGNMENTS
RS485 2-Wire half duplex is used to connect several devices to the same bus when only one unit
transmits data at a time. All units are normally in high impedance receive mode waiting for data. When
transmission of data is requested, the device waits for a protocol specific turn-around time delay before
transmitting after which it returns to receive mode.
RS485 4-Wire full duplex is used for master/slave arrangement. Devices are polled and respond faster
with no turn-around time delay required between request/response. The receiver is always enabled
allowing the devices to receive data even while responding to a request.
Note: If a link doesn't seem to be working correctly (no communication or just one way
communication), try swapping the polarity of the data lines on both ends. Some devices are marked
opposite the RS485 standard.

3MAINTENANCE
3.1 INTRODUCTION
The following section outlines the fault-finding procedure for the OSD8327T and OSD8327R modems.
Please take note of the following:
▲ Personnel without appropriate training should not attempt any maintenance except that outlined
below.
▲ If further maintenance is attempted you are warned that every care should be taken to ensure that
internal measurements made while the equipment is operational are taken carefully as some
components within the unit are expensive and may be damaged by failure of any portion of their
support circuitry.
▲ Some components within the unit are Electrostatic (ES) sensitive and Electrostatic Discharge
(ESD) precautions should be taken when performing maintenance upon the unit.
3.2 EXTERNAL INSPECTION
Visually check for the following:
▲ Check that the correct power source is connected to the power socket.
▲ Check that the HD/SDI and data signals are connected to the modem correctly and that the distant
OSD8327T or OSD8327R modem has been terminated correctly to any external equipment.
▲ Inspect the optical connectors for any contamination and clean using isopropyl alcohol and a lint
free tissue if any contamination is detected.
▲ Check that any external termination resistors are connected if the system configuration requires
them.
3.3 ROUTINE MAINTENANCE
▲ There is no routine maintenance required with the OSD8327T and OSD8327R.
